This application is a division of oui` copending application, Serial No. 235,850. p The invention relates to an improvement ,in airshipmooring masts and will be b est understood from the following description and the annexed drawing, in whlch the single figure is a vertical section through a tower head and mooring mast showmg'our invention.

The outer tube 1 of the mooringvmast 1s supported in gimbals2 mounted in known manner in a frame 3 which is ri idly connected to the tower structure 4. h e inner tube 5 which is provided with a piston' 6, lisis movably mounted in, the tube 1, wh 1ch thus forms a cylinder,` cooperating with the piston. The upper or outer end of the tube 5 is provided with the usualcup 7 to receive the nose of an airship, and visv provided v 20 at itsinner or lower end with an extension or tail rod 8 passing through a gland or stuffing box 9 and having at its lower end a cone shaped'spigot 10 adapted to be received in a socket member 11. The socket 25 member is in the form of a iston which may be raised or lowered by uid pressure suc as air supplied at two different. pressures from. lthe reservoirs 12 and 13, 1n the manner described in our aforesaid c opend- 80 in application.

he mainv haul rope 14 passes down through the hollow piston 5 and over a pulf ley 15 supported in'- a bracket at the lower ond ofv the mast. The rope then passes around pulleys 16 on the imbal frames, and thence to the'ground. Sguitableconnections indicatedat 17 are adapted to conduct Huid pressure to the cylinder formed bythe tube 1, controls 'for all ofthe fluid pressure lines being situated in the housing 18. Centering ropes, one of which is shown at 19, are secured to the mast, running Aover Y pulleys 20 on the tower and pulleys 21 on the mast, both of these pulle s being mounted on both horizontal and).7 vertical' axes, as shown. The pulleys 21 are mounted in a crosshead 22, slidably mounted on the tail` rod 8, and the ends' of the centering ropes Vare secured tothe mast proper as in-` dicated at 23. l

Mounted on the mast are one or more cylinders 24 containing pistons 25 adapted to engage the crosshead 22 preferably adja-l cent one of the pulle s 21. The cylinder 24.- is disposed inthis orm beneath the c 1- inder formed by the tube 1, and is ver-tica disposed as shown, its upper end being connected by a pipe 26 to the cylinder 1 in such a position that the port at the upper end of the pipe 26is uncovered when the piston 6 is in its lowermostl positionhasshown in the drawing. By this arrangement, when 'the port at the upper end of the pi le 26 is uncovered, the fluid inl the cylin er 1 passes into the cylinder 24 and thus o crates the piston to force the crosshea 22 longitudinally of the tail rod and thus automatically center the mast. On the u ward movement of the piston 6 the fluid 1n the cylinder 24 may exhaust through the pipe 26 back into the c linder 1. v

While the c lin ers 24 are shown as being supplied wit fluid from y through the pipes 26, neverthe ess we may find it desirable under certain conditions to operate the pistons in these cylinders by fluid from some other source, so that the cylinder 24 may be operated independently of the operation of the piston 6.
